<P>PROBLEM TO BE SOLVED: To provide a nanofiber sheet which comprises nanofibers including a volatile functional agent such as a perfume or the like and is capable of providing a useful function such as scent-emission by an action of the volatile functional agent. <P>SOLUTION: A nanofiber sheet of this invention is provided with a nanofiber layer including nanofibers of high polymer. The nanofibers contain a volatile functional agent and have a vapor pressure at 20°C of 13.3 Pa or less. Preferably the nanofibers are formed by an electrospinning method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
